<div class="block">This sets the reader to use to retrieve the underlying bytes to process.
The reader may perform buffering or other operations before making the
data available.
Subclasses should override this method if additional actions need to be
performed when the reader is set, typically this will be things such as
an initial read of the data.</div>
